Abstract

PURPOSE:To make efficiently a truly circular wire of an extra small diameter as well with die grooves by housing plural pairs of shaft-shaped revolving rollers having the plural die grooves into a roller box in such a manner that the rollers contact alternately with the wire to be worked from the top, bottom, right and left and rotating cooperatively all the rollers. CONSTITUTION:The front end of the wire, when inserted through an insertion hole 9 provided to the roller box 1, is engaged with the grooves 2 of the revolving rollers 3 and is then engaged with the grooves 2 of the rollers 3 which are positioned successively thereafter and are alternately provided to the top, bottom, right and left. The wire is thus successively rolled from vertical and lateral directions. The shaft-shaped rollers 3 are extremely small in diameter as compared with the rolling force and therefore the roller pitch is short and all the rollers revolve. These rollers are freely rotatably fixed in the roller box in such a manner that the surfaces of all the rollers fixed to each other provide the datum plane. The turning of the wire in the grooves 2 is thereby averted and the deviation of the rolling down direction and the rolling angle of the wire is obviated.

The present invention relates to a rolling wire forming apparatus.

〔従来の技術〕[Conventional technology]

現在、通常使われている金属線は、線材を孔ダイスから
引き抜く伸線加工機を使用して製造している。Currently, metal wires commonly used are manufactured using a wire drawing machine that draws the wire through a hole die.

、組成変化を起こす場合もあった。However, wire drawing machines that use this drawing force generate drawing stress in the metal wire itself, and the area reduction rate that can be safely processed is determined by the relationship with the tensile strength of the wire itself. When processing at high speeds, the wire sometimes broke. In other words, if the ratio of area reduction rate to tensile strength is 70% or less, it will be safe and there will be no problem.However, in order to improve production efficiency, it is desirable to increase the area reduction rate as much as possible, but if the ratio of pulling force to tensile strength is 100% or less, %, the wire will break during wire making. Therefore, it is currently difficult to improve production efficiency. In addition, the stress and strain applied to the interior of the metal due to the pulling force may cause compositional changes.

った。For this reason, in order to make wire from metals that are difficult to draw due to drawing force, we have improved the shape and material of dies, developed lubricants to reduce sliding friction, and pre-processed processes such as resin processing and oxide film treatment. was developed, but it did not provide a fundamental solution, did not improve productivity, and was particularly difficult to process difficult-to-process metals such as titanium.

この為、線材に前記の如く問題を発生させる引抜力を加

の間にダイスを形成し、このダイスにより線材を加工す
る方法及び装置を、先に出願した。For this reason, as a wire making device that does not apply the drawing force that causes the above-mentioned problems to the wire rod, a die is formed between a pair of rotating rollers provided with grooves, and a method and apparatus for processing the wire rod with this die are proposed. I applied first.

悪く、しかも真円にならない線材しか得られない。However, rolling equipment using rotating rollers uses a roller die that gradually reduces the diameter of a round wire to gradually reduce the diameter from the top and bottom and from the left and right until it reaches a predetermined thickness. Since a circular wire cannot be directly thinned into a circular shape, it is first made into a modified circular shape and then made into a thin circular shape.At this time, if the wire itself is not twisted and has a predetermined crimping angle, it is possible to roll with high precision. It can be processed, but if the wire slips and twists in the roller die, the rolling angle of the roller and the crimping angle of the wire will be misaligned, and the wire will remain oval rather than circular, resulting in poor dimensional accuracy and the wire will not be perfectly round. Only wire rods that cannot be obtained can be obtained.

That was difficult.

が起ったり切断することがない。To manufacture a wire rod using the apparatus of the present invention, the wire rod is inserted through an insertion hole provided in a roller box. As a result, the tip of the wire rod is caught in the grooves of the driving and rotating rollers, and as the rollers rotate, the tip of the wire rod is bitten in the grooves of the rollers located at the rear, which are arranged alternately in the upper, lower, left and right directions, and the wire rod is sequentially rolled from the upper, lower, left and right directions. I can do it. The shaft-shaped roller according to the present invention is very thin compared to the rolling blade, and therefore the roller pitch is short (also, all the rollers are driven and rotated, and all the rollers have their roller surfaces fixed to each other). Since it serves as a reference surface and is rotatably fixed in the roller box, the wire does not rotate within the groove of the roller, the rolling direction of the roller and the rolling angle of the wire do not deviate, and the roller does not align with the axis. Since the diameters are almost the same, it is possible to obtain large rigidity and rolling edges, and it is possible to roll with extremely high accuracy, and it is possible to successfully produce thin wires, which was difficult until now.Also, since no drawing force is applied to the wire material during wire production, The wire does not undergo compositional deformation or breakage due to strain.

Since it is rotatably fixed in the box and all the rotating rollers are rotated in conjunction with each other, perfect circular wire rods with excellent precision can be produced with high production efficiency, from thick wire rods to extremely thin wire rods. It produces the effect that can be achieved.
